building a new pc
My fingers are getting itchy to build a new pc again. I want to make =
the switch to 64bit and don't want to settle for the AMD 64 3200+ and = its 64 bit memory controller when the FX and the Opteron have 128. The = thing I'm wondering about though are the hyperthreads. The 64 FX has = one hypertransport link and the Opterons have three. The Opteron 146 = links are "incoherent", the 246 has one coherent link and all three of = the 846's links are coherent...whatever that means. The 64 FX starts = right off the block as more expensive than the Opterons and seems to be = less capable than the Opterons. I'm leaning towards an Opteron 246. = Anybody have some insight as to what the extra hyperthreads and whether = or not they are coherent will do for the average destop/game machine? = The FX is a 2.2GHz and the Opteron X46 series are 2GHz so I don't see a = whole lot of advantage there or reasoning for the extra expense. Any = help would be appreciated. DougH |

Considering the expense of the cpu and ECC ram, reports of early chipset problems, I think you should wait awhile, until people knowing exactly what they're buying and why, have leveled the way. There's no experience of these systems yet. I'm more tempted by the 64-bit bus version. Much, much cheaper. Cpu, mobo. ram. Hypertransport is not the same thing as hyperthreading, by the way. Hypertransport is a point to point bus that connects to AGP, PCI, southbridge and other cpus. Wild (well maybe not) guess, I haven't checked this, the coherent link is for connecting to another cpu. The 146 is for use as single cpu. 246 is for dual systems, thus it needs 1 coherent link. 846 is for eight cpu systems. In a such, 4 cpus connect to three other cpus, that's probably why it needs 3 'coherent' links, other 4 connects to two other cpus. ancra |

Any = help would be appreciated. Oh, and I forgot... A single Opteron has lower memorybandwidth than the AthlonFX. So there is a difference. In a dual Opteron setup, one Opteron has higher memorybandwidth than the AthlonFX. Because it can use the co-cpu's memorycontroler too, over the HT-link. You have to check out benchmarks, to see if one Opteron makes sense as a desktop, considering the cheaper A-64 (and cheaper ram, and mobo).. ancra |

it is *NOT* worth 64bit machining yet.
get a cheap mid-range pc (2500+ barton etc) and save your penies untill windows Longhorn (XP2) comes along late 2004/early 2005. this will be the first show 64bit MS OS. then wait another 6 months or so for the first programs on 64bit. also gives chipsets, cpu's, and standards to be tweaked. tim "DougH" wrote in message ...

DougH Aren't there already 64bit ports of MS windows NT ? unixes ? linux64 ? And as for apps, I definitely remember running 32 bit programs on 16bit Win3.11, with the appropriate win32s library support (thats before and during the proliferation of win95 which is still partially 26bit). So actually 64bit programs can be developed and run before 64bit OS's are widely installed. If chipsets are not ready for the job, then it's no use, ofcourse... |
